you can prevent an apple from browning by adding lemon juice to it
Use lemon juice
Lemon Juice (i tried)
Coating freshly cut apples in sugar or syrup can reduce oxygen diffusion and thus slow the browning reaction. Lemon or pineapple juices, both of which naturally contain antioxidants, can be used to coat apple slices and slow enzymatic browning
Apple only brown due to oxidation, or the apple is being exposed to the air. To slow or even stop the browning of an apple, put it in an air-tight container, or seal all the air out.People have said that soaking the apple in lemon juice for about 5-10 minutes will help stop the browning of the apple, but it is just an old tale, but is worth a shot.
If you put lemon juice (or any other citrus fruit juice) it will slow the browning process known as oxidisation.
If you keep the cut apple under water if will stop the oxygen in the air to react with the apple and no browning will occur.
An apple called Arctic Apple has been genetically modified to be non-browning.
Normally in cooking cut apples are sprinkled with lemon or lime to slow oxidation (browning). Vinegar will also work depending on what you need the apples for.
The vinegar will cause more browning on a red apple rather than a green apple because i did it for my science fair! and that was the results.
chemical reaction.
Browning of the apples is caused by the oxidation of the enzyme phenol oxidase:phenol oxidase + oxygen---------------melanins
Well, some people just like it. Maybe you are wondering 'Why the heck are they doing?' but i do it 2 just cause it makes the apple more sweeter. **But actually, the lemon juice prevents the apple from browning; this also works for other fruits like bananas and pears.**
Lemon juice preserves the apple and keeps it from oxidizing. People use it on apple slices to prevent them from browning. It does not make them rot.
